The results of the waste analysis at inlet and outlet indicated that the efficiency of WWTP in the plywood industries was high at 67% to 99%, with the water discharge 0.007 m 3 /m 3 of product. On the basis of the Degree of South Kalimantan Governor No. 036 of 2008, the maximum discharge is 0.30 m 3 /m 3 of product in order to meet the quality standards. Sludge at WWTP can be used as a mixture of adhesive (filler).
